1u psu for the newest gpu's

kanuseeme · Aug 30, 2014

Will this 1u psu power the lastest gpu's on the market? http://athenapower.com/product/power-supply/1u-2u/ap-u1atx70
ATX Connector 24 (20+4) Pin x 1
EPS-12V 8 Pin x 1
EPS8 (4+4) 8 Pin x 1
SATA 15 Pin x 6
Molex 4 Pin x 5
Floppy 4 Pin x 1
PCIE (6+2) Pin x 1

I know it has only one PCIE . Which would be better to get the 2nd PCIE from 2 sata or 2 molex cables?
I am going to make a low profile case and the height of a 1u psu is ideal for my project.

Or would this psu be a better option?http://www.ebay.co.uk/itm/NEW-Sparkle-700W-1U-ATX-IPC-DUAL-2-FAN-POWER-SUPPLY-SPI4001UG-B204-SPI500U4BG-/321461590388?

Both are 700W, so you'd have to see if your whole setup can run on that. It's a good amount of power for a mid-grade system.

Depends on the GPU. You have a lot of watts, but the amps is kind of low. For example a system with a gtx 770 comes with a recommendation of 600W and 42A on the +12v rail. Both of the PSUs you are looking at carry 43A. So assuming those PSUs put out their stated numbers, it should barely be ok to power your system with that GPU. As you said, you will need a molex -> PCI-e adapter. Those are never recommended, but a guys gotta do what a guys gotta do, right?

I'm not saying it will work. I'm not saying it won't. That's a tough call in this case. It'll depend on which gpu you want to play with.

That's not a good PSU and shouldn't be used with newer cards.

Thanks a million for the replies, was not expecting 3 and I am sorry for not getting back to you faster.

ok so the 2 psu's are not great. I have found another one which I would like your opinion on. It has more amps and more watts but the problem is that it does not have 8 pin pci-e connectors but 4 x 6 pin pci-e.

OUTPUT WIRES:

1 x 24 PIN --- 18"

2 x EPS 8 PIN --- 18"

1 x P4 4 PIN --- 12"

4 x PCI-E 6 PIN --- 28"

4 x SATA --- 12"

Would it even power a gtx titan z?

Thanks again
