ASRock is a very highly regarded company in the PC sector, and while some of their products have fallen short of the mark, over the years they have earned a good reputation among the enthusiast audience. Right now ASRock have not given me confirmed UK pricing for the SL-1200GW, or anywhere in the world for that matter, which makes it tricky to offer concrete buying advice. I will, however, take a fairly educated guess and assume that the SL-1200GW power supply will be competitively priced when it hits Europe and the United Kingdom.
The SL-1000 GW power supply, for instance, is on sale now for £169.99 in the UK, so I would imagine this higher power 1200 Watt model will be around the £199.99 inc. VAT price point.
First impressions are good. The white matte finish looks clean, and the power supply has some little flourishes around it which indicate that ASRock have put a little time and effort into the design. The modular bay is well laid out, and the cable quality is very good overall. Everything is white as well, which while expected, is not always the case!
Technically, the unit doesn't fail to deliver – load regulation is very tight and the unit is able to deliver continuous high levels of power for even the most demanding of systems. It handled the cross load tests without any issues as well, which is always good to see. The adoption of a quality fluid dynamic bearing fan and high grade 105C rated capacitors from Rubycon and Nippon Chemi Con show that ASRock means business, further exemplified by the 10 year warranty in place.
Fan noise is a little higher than I would have hoped, but the fan profile is set to be rather aggressive, especially when loads get higher. It wasn't annoying (well, for me, anyway) – but if you are susceptible to fan noise and are constantly running with a 900 Watt load, this may be something to consider before dropping your hard-earned cash.
The only real disappointment for me is the somewhat ‘average' ripple suppression. It is not something you would need to be concerned about if you are considering a purchase, but in 2025 I would expect these results to be a little better (lower). Positively, all the protection features worked as they should.
Overall, I would say the ASRock Steel Legend SL-1200GW is a very capable supply which delivers quality power. The overall quality of build, matte white finish, and high grade materials ensure the unit will look good slotted into a white build. We like the adoption of 105C rated Japanese capacitors and the 10 year warranty brings peace of mind to the end user.
Pros:
- 10 year warranty.
- 105C rated Japanese capacitors from Rubycon and Nippon Chemi Con.
- Fully modular.
- Quality matte white finish.
- 150mm long.
Cons:
- Can get a little loud under high load situations.
- Ripple suppression could be better.
KitGuru says: Another great power supply from the ASRock and HEC partnership. High grade materials and quality components inside ensure this unit delivers quality power right up to 1200 watts. It also looks great!
