Power supply & R7 370

[FractalXX]

Welcome.

I'm going to buy a new gpu in the near future (possibly R7 370) and I'm not really sure how to check if the amps on the 12v in my PSU are enough for the card.
Some sites said the 370 needs ~33A on the 12v rail. Some said lower.
Firstly, how much does it really need?
Secondly, would my PSU be able to power that fully?
It's a 650W HP PSU (so wattage is not a problem), and here's the picture of it (found on google, but it's the same):

I'm not really sure what are those D, B, and M rails, CPU0 and CPU1 are self-explanatory I guess. (I have a workstation with multiple CPUs, HP xw6600)

Thanks in advance.

First, which model of the R7 370 are you planning on getting, different board partner models will consume different amounts of power.

Your Delta made HP power supply is fine for most any GPU up to GTX 980 or R9 380X as long as it has the PCIe power cables to run power to the new GPU and as long as it's not really old and worn out.

Its a delta unit & will power a 370 EASILY mate.

All you need to check are the power connectors on there for GPU.

They'll be marked GPU or pci-express & I fullyexpect it to have 2xcables with 6+2 pins that look like these

You should be fine , the Draw of the card depends on the version they vary from Stock to the Overclocked. Now before someone chimes in and says you need to replace that supply I will say Delta makes supplies for Antec so they are not bad at all.

You can convert the Watts to Amps here. http://www.rapidtables.com/calc/electric/Watt_to_Amp_Calculator.htm

This actually, but maybe I'll save a little more and get the 4GB Nitro.

Edit: Wow, that was fast. Thanks to all of you.
I forgot to mention I do have 2 6pin connectors.

 

[madmatt30]

It would appear as that's a server based PSU it may only have a single 6 pin for GPU.
If this is correct then as its uncertain how the rails are setup you may be safer going for a gtx 950.

The 370 you listed is single 6 pin so is fine

 

[FractalXX]

I have two 6-pin PCI-E connectors, but I'm not sure if they're 6+2, or just 6. (I haven't opened the case for a while)
Also, the motherboard is CF compatible, and I haven't made any modification to the workstation (except for more RAM and my current HD 7750), yet, so I guess it won't be a problem as it's designed for 2 cards.

Specs everywhere for that PSU state single 6 pin as does the post above.

Are you running a pair of 2ghz xeons in there still??
If so that low base clock won't perform great in games so a 370 or 950 would be the max I'd use anyway.

 

[FractalXX]

Yes, that's one reason I won't go any bigger regarding graphics cards. There are two 2.5Ghz quad-core E5420 Xeons in there with 16GBs of RAM.

What country are you mate ??

 

[FractalXX]

Hungary. Why? And you?

 

[madmatt30]

UK , if you'd been UK I could have pointed you to a couple of great deals is all.
