Hi everyone, Recently my 4 year old computer conked out, and I’ve confirmed that the cause is PSU failure through the use of a friends’ computer. I need a replacement and am not concerned about including the potential for future upgrading. The computer was originally a MESH package deal but is now out of warranty (which considering the current state of MESH seems good timing). My current build is shown below: Case – Aluminium ATX Midi Tower Motherboard – ASUS P5NE-SLI Power Supply (BROKEN) – HEC-550TD-PTE Total Power 550W, +5V & +3.3V Combined 185W +3.3V – 30A +5V – 38A +12V1 – 18A +12V2 – 17A -12V – 0.3A +5Vsb – 2A Processor – Intel Core 2 Quad Q6600 (B3) Processor @2.4 GHz, 8 MB Cache, 1066 MHz with Arctic Cooling Freezer 7 Pro Rev.2 CPU Cooler RAM – 4GB (2x2GB) OCZ PC2-6400 Dual Channel DDR2 Graphics – ATi Radeon HD 4850 512 MB Hard Drives – (1 x 500 GB & 1 x 250 GB) SATA with 16 MB Buffer DVD Drive – LightScribe Super Format 18x Dual Layer DVD (Re)Writer Sound Card – Creative Labs Sound Blaster X-Fi Xtreme Gamer Sound Card Other PCI Cards – Digital & Analogue TV Tuner PCI Card Ports – 6xUSB 2.0, 2xFirewire From looking at the (very helpful) forums here and checking some prices, I think my best bet would be to buy the Seasonic S12II-520 520W ATX12V Standard Power Supply Unit – Bronze (amazon link: http://www.amazon.co.uk/Seasonic-S1...-Supply/dp/tech-data/B00390P1NO/ref=de_a_smtd) for £68.08. I think my total draw is around 380W and from an online PSU calculator it recommends at least a 430W PSU. My question to the forums is: Is this a good choice for a replacement PSU? I welcome any comments and/or other recommendations, but I don’t really want to spend more than about £80 on this. Let me know if you need any more information. Thanks in advance, Shisnu.
