content: Hi all ive just brought these,AM3+ Motherboard Bundle W/ AMD FX 8350 /GIGABYTE GA-78LMT-USB3 Micro ATX,4GB PC3 DDR3 MT8KTF51264HZ-1G9P2 SODIMM Micron Memory RAM,ASUS ATI Radeon HD 5770 (EAH5770 Cu Core/2DI/1GD5/A) 1 GB GDDR5 SDRAM PCI.Akasa AK-CBPW10-15BK 4 pin to 8 pin ATX PSU adapter cable,what sort of games etc would this lot be capable of running?,also can the 4 to 8 pin cable for the graphics card be hooked up,ie soldered to one of the 4 pin molex connectors,as i brought the wrong cable,the 8 pin male end has4 yellow wires and 4 black,am i rite in thinking the yellow wires are for +12v and the black ones ground?,cheers m3vuv.

content: I suggest upgrading your RAM to at least 8GB and a SSD for the OS.There are no 4-pin PCIe power connector. PCIe power connector is either 6 or 8 pin. A 4-pin power conector is an ATX12V connector. Some motherboards use a 8-pin power connector, known as EPS12V (or just EPS power connector). Don't mix them up - you can actually insert an 6-pin PCIe connector into an EPS12V (two of the pins on the motherboard would be left out but the connector will fit the keying) but they are wired differently and powering up a system with a wrong connector plugged will result in a catastrophic event.For checking which games your CPU/RAM/VGA combo can handle:https://www.pcgamebenchmark.com/You can also check individually here:https://www.systemrequirementslab.com/cyri

content: RAM is not compatible with motherboard, it simply will not fit. You won't be able to play modern AAA games with any bearable performance. You are basically limited to older games, strategies which usually have lower requirements or casual games/2D. 4 pin cable from PSU can be inserted into 8 pin connector on motherboard and it will work just fine. Those wires are simply connected in parallel and 4 wires are completely enough if not doing extreme overclocking. Cables for GPU and motherboard are not compatible. They have different keying and are impossible to insert into different connector (without hammer).

content: Quote from: m3vuv on August 31, 2020, 04:57:35 pmSuch adapters are a complete waste of money. You simply add another piece of cable between connectors which already fit. The only thing it adds is voltage drop over it.

content: Quote from: wraper on August 31, 2020, 04:10:47 pmwhy the mentioned DDR3 RAM wont fit into the mentioned DDR3 supporting MBoard?Quote from: wraper on August 31, 2020, 04:10:47 pmi bought HP Z800 a while ago that has slower CPU than the mentioned AMD FX 8350 (except 24GB RAM), i only upgraded it with used (mining) Radeon RX480 and SSD. it now can run Titanfall and modern CAD beautifully. unless someone want to play at 8K or 30-60fps means unbearable to him. AAA/3D games today dont use CPU and RAM much. heavywork will be mostly on the GPU card. and i think the mentioned Radeon HD 5770 with only 1GB GDDR5 is a bit old and limiting (similar to what i currently used HD4650 on my main-old-PC-not-for-game). i suggest buying a used 4GB GDDR5 RX480 or RX580... used/mining unit can be bought at $50-100, choose the cleaner one...

content: only DIMM.. check the picture it should be the longer one... and also check your motherboard specification for compatible memory speed, maximum capacity, cpu compatibility (even if same footprint package type) etc etc. this is the 101 for dummy basic you should must do for every diy custom pc build, otherwise one day you'll say diy pc building is sux... if you bought it locally, you should have asked the seller if everything is compatible to each other. ymmv.

content: Quote from: m3vuv on August 31, 2020, 04:57:35 pmThat's an ATX12V to EPS12V.The commonly named "MOLEX" connector on PSUs refer to the old power connector for HDDs/optic drives which is actually designed by AMP.

content: Quote from: m3vuv on September 04, 2020, 05:44:27 amIt will, but it's a complete trash. You should rather buy quality PSU with lower power rating, say 350-450W rather than trash with inflated numbers. You don't need that much power anyway.

content: any idea what i should look for is called as i need the 8 pin connectors for the mb and 6 pin for the graphics card+the power for the sata drives ,looks like the mb main connector is 24 pin,sort of confused what exactly to look for as there seem a few different types,cheers m3vuv.

content: Quote from: m3vuv on September 04, 2020, 11:00:41 amThe first picture I posted here already have all the names for the connectors. A SATA power connector is just known as "SATA power".I suggest a Corsair CX450/CX550. Very capable, modern and somewhat cheap PSU.For reference:https://www.corsair.com/uk/en/Categories/Products/Power-Supply-Units/cx-series-config/p/CP-9020121-UK

content: Quote from: m3vuv on September 04, 2020, 10:51:04 ami currently use the so called trash 450 or 500w. Sometime they worked for 5 years sometime only for few months. Why i stick with those trash is because i 1st bought psu with a brand (Gigabyte) at somewhat elevated price, twice! And they both only worked for few months, thats what i call real trash, so i thought i better stick with cheaper trash, they all will eventually fail but at least i've spent little... my previous cheap trash worked for about 3 to 4 years. If not because some of its wires start to break at mobo power connector, it will be still used today, functionally its still providing proper voltage at psu end.. Otoh regarding 8 or 6 pin adapter, if its too difficult to find the proper one, you can just tap the proper voltage (based on given link) from existing psu cable to the pcie 6 pin connector, ymmv.

content: Quote from: Mechatrommer on September 04, 2020, 08:06:27 pmFrom the myriad of things bad PSUs can do, I'll cite three:* Random BSODs/crashes* Fry sensitive electronics (especially HDDs)* Reduce longevity of the whole systemGigabyte (also Corsair, be quiet, EVGA, Antec and a whole lot) does not manufacture PSUs. They use projects from companies like Seasonic, Delta, Chain Well Technologies, FSP, Great Wall, Andyson, etc. Some of those projects are great, while others aren't meant to me touched at all. Before buying anything a quick googling wields a lot of results/reviews.

content: Quote from: LeonR on September 04, 2020, 10:35:41 pmthere are many classes of bad PSU i guess. the few i used didnt have those effect, except maybe the 1st one (BSOD) but there could be many reasons, bad GPU, RAM etc... everything is designed by human after all (subjected to Murphy's law)..
