Seasonic has a series of 80Plus Platinum power supplies in capacities of 660W, 760W, 860W and 1000W. The 660W, 760W and 860W models have now been replaced by new versions, so of course we had to test the new versions of these PSUs.

The new models carry the same EAN bar codes as the original ones, but the product code has a two behind it (SS-860XP2 for the new model, where the old was called SS-860XP for example). However, it seems that some online shops are selling the new versions under the old product code, so when you order one of them it's unclear which version you're ordering. Fortunately the original has been end of life for a long time, so you can be 99% sure you're getting the new one when you order the 660W, 760W or 860W model.

Since the arrival of the first Platinum power supplies at the end of 2011 prices have dropped quite a bit, but they're still not cheap with average prices of £120, £138 and £184 / € 154, € 187 and € 211. If you read our recent review of the Corsair RM Series 750W, you'll know that you can buy a very good 750W 80Plus Gold PSU for less than £100 / €120.
