Hey guys I got a HP Pavilion HPE H8-1287C, the PSU and GPU suck on it. I just ordered an Asus 7850 1gd5 GPU for it, but now i need a PSU, I've did a bit of research on it, heres what i know so far.
- The 7850 card is pretty good as far as power consumption
- but due to the i7 CPU and 12GB Ram i will need more power
- in my other post, someone recommended a 750w PSU
- Some of the brands i should stick to is Corsair, Antec, Seasonic.
Now this is where i'm confused, I have read some people bought the wrong power supply that is not compatible with their motherboards / GPUs? how can I avoid this issue? Also how can I get a power supply that will best fit my computer (size wise), I know all of HP has their hardware proprietary, so what is the best way to go about this?
For a system using a single reference design Radeon HD 7850 graphics card AMD specifies a minimum of a 500 Watt or greater system power supply. The power supply should also have a maximum combined +12 Volt continuous current rating of 27 Amps or greater and have at least one 6-pin PCI Express supplementary power connector. Some of the non-reference design Radeon HD 7850 graphics cards require at least two 6-pin PCI Express supplementary power connectors. The ASUS HD7850-DC-1GD5 only requires one 75W 6-pin PCI Express power connector.
The HP Pavilion HPE h8-1287c Desktop PC uses the standard ATX PS2 form factor physical dimensions (i.e. 150mm (W) x 86mm (H) x 140mm (D) / 5.9"(W) x 3.4"(H) x 5.5"(D)) for the power supply unit. The depth may vary depending on the power supply's capacity rating.
The power connectors, on the Pegatron motherboard, all adhere to the ATX12V specification so they are not HP proprietary.
I would like it to be as cheap as possible, under $100 if i can.
The Seasonic S12II-520 Bronze (SS-520GB), with its maximum combined +12 Volt continuous current rating of 40 Amps and with one 6-pin and one (6+2)-pin PCI Express supplementary power connectors, is more than sufficient to power your system configuration with a single Radeon HD 7850 graphics card.
